After Su Qin's death, his younger brother Su Dai sought to carry on his legacy. He journeyed north to have an audience with King Kuai of Yan, saying: "I am but a humble man from the Eastern Zhou, and having heard in private of Your Majesty's lofty virtue, I have come to offer my humble service in admiration. Today I serve Your Majesty, yet not for personal gain. I have heard that a loyal minister serves not two lords, and a chaste woman weds not two husbands. Now, if Your Majesty desires to establish merit and renown, I beg to present my counsel." The King of Yan said: "I am willing to hear your strategy." Su Dai replied: "I have heard that a wise sovereign devotes himself to heeding his own faults, rather than delighting in hearing others speak of his virtues. Now Qi and Zhao are Your Majesty's foes; Chu and Wei are Your Majesty's allies. Your Majesty would do well to keep a watchful eye on the movements of Qi and Zhao, while forging deep ties with Chu and Wei. Moreover, I have heard that opportunity is hard to seize yet easy to lose—I pray Your Majesty will ponder this with the utmost care." The King of Yan said: "Well spoken. I am willing to follow your instruction." Thereupon he rewarded Su Dai generously, bestowing upon him chariots, horses, gold, and silk, and dispatched him eastward on a mission to the state of Qi.

Su Dai carried forward his elder brother's mission, not through blind replication, but by precisely identifying Yan's core contradictions—Qi and Zhao as adversaries, Chu and Wei as allies—and proposing a strategy of "cementing ties with Chu and Wei while keeping a watchful eye on Qi and Zhao." This offers a lesson for modern business: successors or new entrants must redefine competitive and cooperative relationships based on their own resources and the market landscape, rather than mechanically copying their predecessors' playbooks. For instance, when Huawei expanded into overseas markets, it did not confront Western giants head-on; instead, it forged alliances with local carriers (akin to the support of Chu and Wei) while closely monitoring competitors' patent portfolios (akin to the threats of Qi and Zhao), thereby breaking through in the 5G arena. Su Dai's emphasis that "opportunities are hard to come by yet easy to lose" corresponds to the concept of market windows—ByteDance, for example, launched Douyin swiftly at the dawn of the short-video trend, seizing the first-mover advantage rather than waiting for the market to mature. Furthermore, Su Dai's declaration that "a loyal minister does not serve two lords" was not merely an expression of fidelity but a means of building trust in negotiations—much as modern consultants must first demonstrate expertise and loyalty to secure long-term mandates from corporate leadership. King Yan's generous rewards and heavy delegation of responsibility illustrate that leaders should dare to entrust "second-generation" talent, provided such individuals offer differentiated insights—Su Dai did not resurrect the old framework of vertical and horizontal alliances, but instead presented a new vision of geopolitical balance. This is precisely what second-generation managers in enterprises should embody: while inheriting a legacy, they must deliver strategic iterations adapted to a changing environment.
